Description

Technical Field

[0001] The present application relates to the technical field of sunshade equipment, and specifically to a die-cast installation code and sunshade equipment. Background Art

[0002] Sunshade equipment, especially windproof roller blinds, are generally used in outdoor pavilions, balconies and other places. Its functions include windproof, rainproof and sunshade. Its structure consists of a shell assembly, a mounting code, a fabric drive assembly, a guide rail assembly and a bottom rail. The mounting code plays the role of fixing the shell assembly, fixing the fabric drive assembly and connecting the guide rail. Because the mounting code needs to be assembled with multiple unused parts, and the assembly methods of each part are different, it is difficult to complete the manufacturing with one part and one structure. Generally, the mounting code is assembled by screws or welding from several stamped and bent parts. Different stamping and bending parts require different molds, welding fixtures, testing machines and other equipment to support them. There are many production links and a long production time.

[0003] The installation order of windproof roller shutters is generally to first fix the shell assembly with the installation code, then put in the fabric drive assembly, and then put the installation code into the structure corresponding to the guide rail assembly, and finally fix the guide rail assembly to achieve the purpose of fixing the entire mechanism. When the windproof roller shutter is installed on the ground, the uneven ground will affect the levelness of the fabric assembly, which will affect the normal operation of the roller shutter. And because the windproof roller shutter is a soft decoration product in the decoration, the installation cannot destroy the original decoration style, and the levelness cannot be guaranteed by adjusting external factors as much as possible. Therefore, the installation code needs to have the function of adjusting the height, height and horizontal angle of the fabric drive assembly. Utility Model Content

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a die-cast mounting bracket and a sunshade device, wherein the mounting bracket is integrally die-cast, which reduces the production process of the mounting bracket and the connecting parts between the structures, so that the mounting bracket can adjust the height and level of the slide rail internally without external adjustment (for example, adjusting the height of the guide rail to make the mounting bracket level), thereby improving the service life of the sunshade device.

[0005] A die-cast mounting code of an embodiment of the present application includes: a left mounting code, a right mounting code, a first fastener, a second fastener, a third fastener, and a slide rail. The left mounting code and the right mounting code are metal die-castings. The left mounting code and the right mounting code are symmetrical structures with the same characteristics, including a first limiting portion, a second limiting portion, and a third limiting portion. The second limiting portion is provided with a first through hole, a second through hole, a third through hole, a first groove, and a second groove. The first limiting portion is provided with a first connecting hole, and the second connecting hole is arranged below the second limiting portion. The first groove and the second groove are provided in A third fastener is respectively provided, the first fastener passes through the first through hole and the second through hole respectively to be connected with the third fastener, the second fastener passes through the third through hole and is assembled with the first connecting hole, the first limiting portion, the second limiting portion, the third limiting portion and the third fastener form a cavity for placing the slide rail; the upper and lower positions of the slide rail can be adjusted by screwing in and out the first fasteners of the first through hole and the second through hole at the same time, and the left and right inclination angles of the slide rail can be adjusted by screwing in and out with different numbers of turns, constituting a die-cast installation code provided by one aspect of the present application.

[0006] In a possible implementation, all features of the left mounting bracket and the right mounting bracket except the threaded features are integrally die-cast, and the first connecting hole and the second connecting hole are firstly cast with bottom holes during die-casting and then processed with threads through subsequent machining.

[0007] In this implementation, the features of the left mounting bracket and the right mounting bracket except the thread feature can be prepared by die-casting, which reduces the number of connected parts and simplifies the processing procedures.

[0008] In a possible implementation, the left mounting bracket, the first limiting part and the second limiting part of the right mounting bracket are first die-cast into a main structure by a mold, and the hole features and thread features thereof are processed by subsequent machining. In this implementation, the use of sliders in the mold can be reduced, thereby reducing the cost of the mold.

[0009] In a possible embodiment, the first limiting portion and the second limiting portion adopt a slider core-pulling structure to open the mold, so the first inner side surface, the second inner side surface, the first bottom surface, the second bottom surface, the fifth inner side surface, the sixth inner side surface, the seventh inner side surface and the eighth inner side surface all have a draft angle, which can increase the service life of the mold slider and avoid scratches on these surfaces when the slider is core-pulling.

[0010] In a possible implementation, a third fastener is disposed in the first groove and the second groove of the left mounting code, respectively, the first fastener passes through the first through hole and the second through hole respectively to assemble with the third fastener, and the top surface of the first fastener contacts the side surface of the slide rail. When the two first fasteners are screwed in at the same time, the top surface of the screw pushes the slide rail to move upward, and conversely, when the first fastener is screwed out, the slide rail moves downward under the influence of gravity. When the screw of the first through hole and the first fastener of the second through hole are screwed in different numbers of turns, the left and right tilt angles of the slide rail can be adjusted, thereby adjusting the horizontality of the slide rail.

[0011] In a second aspect, the present application provides a sunshade device, including a cover shell, a winding assembly, a guide rail, and a die-cast mounting code provided in any of the above-mentioned implementation methods.

[0012] The sunshade device provided in the second aspect of the present application utilizes a die-cast mounting code provided in the first aspect of the present application for the connection of the cover, winding assembly and guide rail, and has at least the following beneficial effects: the mounting code is die-cast once, which reduces the weight of the parts, reduces the connection points between the various structures of the mounting code, reduces the processing links of multiple parts, shortens the manufacturing time, and improves production efficiency. The mounting code places the third fastener by setting a groove for the third fastener so that the overall material thickness distribution of the entire mounting code casting is more uniform, improves the pressure resistance and strength of the mounting code, and also saves the material waste generated by subsequent machining. The use of the third fastener instead of the method of directly drilling and tapping the casting overcomes the problem of insufficient load-bearing capacity of the mounting code due to thin material thickness and few screw threads under the premise that the overall material thickness is relatively uniform. The mounting code adjusts the position of the slide rail by screwing the fastener in and out, so that it can achieve the effect of adjusting the height and horizontal angle of the slide rail.

[0013] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become apparent from the description below, or will be learned through the practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] See also Figure 1 to Figure 6 A die-cast mounting code of the present application includes: a left mounting code 6, a right mounting code 3, a third fastener 7, a first fastener 8, a second fastener 9, and a slide rail 5. The left mounting code 6 and the right mounting code 3 are metal die-castings, and the material can be aluminum alloy, zinc alloy, stainless steel and the like. For example, the left mounting code 6 and the right mounting code 6 are made of aluminum alloy.

[0029] The left mounting code 6 and the right mounting code 3 are symmetrical structures with the same features, including a first limiting portion 10, a second limiting portion 20, and a third limiting portion 30. The second limiting portion is provided with a first through hole 21, a second through hole 22, a third through hole 23, a first groove 60, and a second groove 61. The first limiting portion 10 is provided with a first connecting hole 11, and the second connecting hole 40 is located below the second limiting portion 20. A third fastener 7 is respectively arranged in the first groove 60 and the second groove 61. The first fastener 8 passes through the first through hole 21, respectively. The second through hole 22 is connected to the third fastener 7, the second fastener 9 passes through the third through hole 23 and is connected to the first connecting hole 11, the first limiting portion 10, the second limiting portion 20, the third limiting portion 30 and the second fastener 9 form a cavity for placing the slide rail 5; the upper and lower positions of the slide rail 5 can be adjusted by screwing in and out the first fastener 8 of the first groove 60 and the second groove 61 at the same time, and the left and right inclination angles of the slide rail 5 can be adjusted by screwing in different numbers of circles, constituting a die-cast installation code provided by one aspect of the present application.

[0030] The present application provides a sunshade device, including a cover shell, a winding assembly and a guide rail, and a die-cast installation code provided above, wherein the installation code is used for connecting the sunshade device cover shell, the winding assembly and the guide rail.

[0031] The sunshade device in the present application is a device that can rotate to roll up coverings, such as roller blinds, ceiling blinds, etc. For example, the sunshade device is a windproof roller blind, and the left mounting code 6 and the right mounting code 3 are connected to the cover. The cover provides protection, shielding and support for the winding assembly. The winding assembly can roll up coverings such as fabrics, TPU and other materials. The winding assembly can also be provided with a manual clutch, a motor and other driving devices with a transmission function. The guide rail is the bearing member of the mounting code, and the mounting code is carried on the guide rail. Combined with Figure 7 As shown, the figure shows the appearance of the assembly structure of some parts of a sunshade device for a windproof roller blind. In the figure, the winding component 300 is connected to the slide rail 5, and the left mounting code 6 and the right mounting code 3 are connected to the cover 301 and the guide rail 302.

[0032] Since the left mounting code 6 and the right mounting code are symmetrical structures with the same features, this application will not repeat the description for the sake of brevity, and only the left mounting code 6 will be described below.

[0033] In a possible implementation, the first connection hole 11 and the second connection hole 40 are holes that can be connected and fastened, such as threaded holes, through holes, etc. For example, the first connection hole 11 and the second connection hole 40 are holes with internal threads, which can be connected and fastened with bolt-like fasteners. If they are through holes, they can be connected and fastened with self-tapping screws.

[0034] In a possible embodiment, all features of the left mounting code 6 except the threaded feature are integrally die-cast, and the first connecting hole 11 and the second connecting hole 40 are first cast as bottom holes during die-casting and then threaded by subsequent tapping. This can minimize the processing steps and allow the main structures to be prepared through the same process.

[0035] In a possible implementation, the first connecting hole 11 and the second connecting hole 40 are first cast into the main body contour and then machined into the finished product by drilling and tapping. This method can reduce the use of sliders in the mold and save the production cost of the mold.

[0036] In a possible implementation, the first limiting portion 10 and the second limiting portion 20 are molded by means of a slider core pulling method, so the first inner side surface 80, the second inner side surface 81, the first bottom surface 82, the second bottom surface 83, the fifth inner side surface 84, the sixth inner side surface 85, the seventh inner side surface 86, the eighth inner side surface 87, the ninth inner side surface 88, and the tenth inner side surface 89 all have a draft angle, that is, a taper. This can increase the service life of the mold slider and prevent scratches on these surfaces when the slider core is pulled.

[0037] In a possible implementation, in order to make the overall thickness of the left mounting bracket 6 as evenly distributed as possible to improve the strength and pressure resistance of the mounting bracket 6, the second limiting portion 20 is provided with a first groove 60 and a second groove 61 for placing the third fastener 8.

[0038] Because the design of the die casting should try to achieve uniform wall thickness distribution, not too thick or too thin, if no groove is set to place the third fastener and drilling and tapping are performed directly at the same position, in order to make the threaded hole have a larger preload force, there are two preferred options. One is to use a large-diameter threaded hole. In this way, the tapping does not need to be too thick, but the material in the radial direction of the threaded hole will be very thick. The second option is to use a small-diameter fastener, so that the tapping body is thicker and the material in the radial direction of the threaded hole is thinner. Both methods are likely to cause poor density of the die casting and reduce its strength and pressure resistance.

[0039] In a possible implementation, a third fastener 7 is placed in the first groove 60 and the second groove 61 of the left mounting bracket, respectively. The first fastener 8 passes through the first through hole 21 and the second through hole 22 to assemble with the third fastener 7, and the top surface 70 of the first fastener 8 contacts the side surface 71 of the slide rail 5. When the two first fasteners 8 are screwed in at the same time, the top surface 70 of the first fastener 8 pushes the slide rail 5 to move upward, and conversely, when the first fastener 8 is screwed out, the slide rail 5 moves downward under the influence of gravity. When the first fasteners 8 of the first groove 60 and the second groove 61 are screwed in different numbers, the left and right tilt angles of the slide rail 5 can be adjusted, thereby adjusting the horizontality of the slide rail 5.

[0040] In a possible implementation, the third fastener 7 is a part with an internal thread or a pin hole, and exemplarily, the third fastener is a nut. The first fastener 8 and the second fastener 9 are pins or cylindrical parts with threaded features, and exemplarily, the first fastener 8 and the second fastener 9 are bolts.

[0041] In a possible implementation manner, the width of the slide rail 5 is slightly smaller than the width of the cavity of the left mounting bracket 6 to ensure that it can be fine-tuned to tilt left or right.

[0042] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
